I fit two spectral features at approximately 1.33 eV and 1.53 eV. Each was fit with a Lorentzian plus a linear background in a local energy window. The allometric model was \(y=aP^b\); uncertainties below are standard errors from the log–log fits.

| Quantity | Peak 1 exponent \(b\) | Peak 2 exponent \(b\) |
|---|---:|---:|
| Peak intensity vs power | 0.9103 ± 0.0144 | 0.8503 ± 0.0336 |
| Peak position \(x_c\) vs power | 0.004570 ± 0.000106 | 0.001578 ± 0.000381 |

The fitted peak parameters for every power are in [lorentzian_peak_fits.csv](<<BENCH>/raw/commercial/luna-high/bench/t-pl/run-15/lorentzian_peak_fits.csv>); all allometric coefficients are in [allometric_fit_summary.csv](<<BENCH>/raw/commercial/luna-high/bench/t-pl/run-15/allometric_fit_summary.csv>).

RESULT: b = 0.9103 ± 0.0144
